Bug#785595: WebIDE downloads and launches adb binary without prompting; subsequently runs at Firefox startup

Package: iceweasel
Version: 38.0-2
Severity: grave
Tags: upstream

I opened up the developer menu in Firefox 38, and saw the new "WebIDE".
I opened that up to take a look at it, and then closed it, without
running anything else.

That action alone apparently caused Firefox to silently download the
"ADB Helper" and "Valence" extensions in the background (see extension
list below), install them without prompting, and run them.  That in turn
downloaded and ran a pre-compiled adb binary in the background (which
Firefox launches at startup).

While it's potentially acceptable to *optionally* install such
extensions on user request, or even prompt to install them, silently
doing so without user consent in response to opening WebIDE (and doing
absolutely nothing with it) is definitely not OK.

This is upstream bug
